Corrigendum: Determining the effects of clumping and porosity on the chemistry in a non-uniform AGB outflow (Astronomy and Astrophysics (2018) 616 (A106) DOI: 10.1051/0004-6361/201732276)

When calculating the models discussed in the article, CO selfshielding was erroneously not taken into account. The CO photodissociation rates are therefore smaller than those used in the article. The lower photodissociation rate leads to a lower abundance of C and O close to the star, which influences our results. While clumping and porosity still affects the chemistry throughout the outflow, the formation of C-bearing species in O-rich outflows and vice versa is not as large, as their formation depends on the abundance of the deficient element. The chemistry of N- and S-bearing species is largely unaffected. (Figure Presented) (Table Presented).
